IPC: F04C2/18
Filed: 1967-08-21
Abstract: 1,232,590. Gear pumps and motors. DOWTY HYDRAULIC UNITS Ltd. July 30, 1968 [Aug.21, 1967], No.38474/67. Heading F1F. [Also in Division F2] Shafts of meshing gears are mounted in bushes each having a lubricant groove formed in the bore thereof and an inlet conveniently located in a side thereof, said inlet connecting to the lubricant groove and to a space formed between the meshing teeth, which space increases in volume as the teeth pass by thus creating a suction effect and causing lubricant to be drawn through said inlet via said lubricant groove and thus lubricate the bushes. In an embodiment a gear pump 10, Fig. 1, has a casing 11 having an inlet port 12, Fig. 2, and an outlet port 13. Gears 14 and 15, Fig. 1, are mounted on shafts 16, 17 and 18, 19 respectively. The latter are supported by pairs of bushes 20, 21 and 22, 23 which are of 'D'-shaped cross-section. Each bush is provided with a lubricant groove 50, Fig. 2 in its bore; each shaft 16, 17, 18 or 19 has an annular recess 38, 39, 40 and 41 adjacent the side faces of the gears 14, 15; each bush 20,21,22 or 23 has a side-face 44, Fig. 2, adjacent the gears and provided with a slot 51, two of which connect the respective annular recesses (38 and 40 for example) together; and each bush has another side-face 48, Fig.3, remote from the gears and provided with a recess 47 therein, the side-face 48 being formed on projections 28 or 29 of the bushes and the recess 47 being connected to the inlet port 12 by means of a passageway 46. Seals 30, 31 are positioned on the projections 28, 29 respectively. In operation, then the shaft is rotated, the gears 14, 15 rotate, drawing lubricant through the inlet port 12 and discharging the lubricant under pressure through the outlet port 13. The teeth of the gears commence to pass the slot 51 of each respective bush as they separate on leaving the condition of mesh, the inter-tooth space increases in volume, a pressure drop is created so that a pressure differential exists between the high-pressure lubricant present in the inlet port 12 (and the recesses 45) and in the low-pressure lubricant present in the slots 51. Thus lubricant flows from the recesses 45 in the bushes, through passageways 46, into recesses 47, through spaces 49 which are formed in the ends of the shafts remote from the gears, through chambers 36, 37 which are formed in the casing 11, through the grooves 50, into the annular recesses 38, 39, 40 and 41, and into the slots 51.

Abstract: 1,252,193. Gas turbine engines. ROLLS ROYCE Ltd. Sept. 26, 1969, No.47563/69. Heading F1G. A gas turbine engine comprises a ring of angularly spaced apart members 18, which are preferably aero-foil vanes, mounted for movement between an inoperative position in which they are retracted into the outer casing 11, 12 and an operative position in which they entered into the air intake partially to obturate the latter but so as to permit air to flow between pairs of adjacent members, the extent of obturation being such that the air velocity between the members is increased relative to the increased air velocity through the unobturated portion of the intake but remains at a mean value below Mach 1, preferably Mach 0À8 to 0À85, and powered means for effecting the movement. As a result of this rear-source mean air velocity in the region of the vanes 18, the noise waves originating at the tips of the engine blades are attenuated by the air entering the engine in the opposite direction and at a speed which locally matches or generally nearly matches that of the noise waves. The vanes 18 are mounted in sets of e.g., seven vanes on common platforms 20, each platform being movable by a piston 26 through a lever 24.
